Our heavily meat-centered culture is at the very heart of our waste of the earth's productivity.

For me hope isn't wishful thinking or blind faith about the future. It's a stance toward life - one of curiosity and humility.

Recent breakthroughs in science show we have just the capacities we need to face our planet's challenges. We're "soft-wired" for cooperation, empathy, fairness, along with a deep need to "make a dent," as social philosopher Erich Fromm put it. My hunch is that one reason depression is a global pandemic is that the dominant mental map denies so many of us expression of these deep needs and capacities.

I understand, of course, that grain-fed meat is not the cause of the world hunger problem - and eating some of it doesn't directly take food out of the mouths of starving people - but it is, to me, a symbol and a symptom of the basic irrationality of a food system that's divorced from human needs. Therefore, using less meat can be an important way to take responsibility. Making conscious choices about what we eat, based on what the earth can sustain and what our bodies need, can help remind us that our whole society must begin to balance sustainable production with human need.

[O]ur greatest contributions to the cause of freedom and development overseas is not what we do over there, but what we do right here at home.

I get goose-bumps when you talk about Diane Wilson. Who knows where she found that courage? When she was a child, she would crawl under the bed when a stranger came to the house. But in 1989, she found out that her county in south Texas was ranked worst in the country for toxic waste. She wondered if the effluent, dumped into the waters where she and her family had shrimped for generations, might be responsible for the dwindling fish populations. And she suspected that her son's autism might be related to the pollution.

What has dawned on me is that focusing on the "finite planet" frame sends a message that we have gone as far as Nature can take us and therefore we need to give power to forces outside Nature.
